Analog Devices announces the Power by Linear™ LTC3777, a 150V high efficiency (up to 99%) 4-switch synchronous buck-boost DC/DC controller, which operates from input voltages above, below or equal to the regulated output voltage. Its 4.5V to 150V input voltage range operates from a high input voltage source or from an input that has high voltage surges, eliminating the need for external surge suppression de ...

Makers and Arduino enthusiasts searching for a project to keep them busy this weekend may be interested in this awesome Arduino Fibonacci clock created by maker “TecnoProfesor”. may look a little complicated to read the time but once you know how to read it the Fibonacci clock is a great talking piece. Check out the video below to see it in action. Fibonacci was an Italian mathematician and created the Fibo ...

Word clocks are a cool way to tell the time. While they could have probably been built back in the 1960s with a bunch of relays and bulbs, they really only came into their own in the LED-everything era. [Vatsal Agarwal] built one of his own, showcasing his maker credentials. It’s a build that relies on good woodworking practices from the ground up. Maple wood is used for the frame, cut and prepared on a mit ...

Introduction Sometimes it may be necessary to use a display while making a hardware project, but the size and the type of the display may vary according to the application. In a previous project, we used a 0.96″ I2C OLED display, and in this project we will have an I2C 20×4 character display. Project Parts This tutorial will describe how to use 20 x 4 LCD display with Arduino to print a real-time clock and ...

If there’s one thing Hollywood loves, it’s a ticking clock to create drama. Nuclear weapons, terrorist bombs, and all manner of other devices have been seen featuring foreboding numbers counting down on a series of 7-segment displays. In this vein, [deshipu] developed a rather ridiculous take on the classic trope. The project is built around a ticking four-digit display. The blue LEDs give it a modern touch ...

Digital clocks are extremely useful and generally considered pretty easy to read. However, they can sometimes have rather arcane interfaces for setting the time and alarms. For [Michael Wessel], he noted that in the 1980s he had to routinely help his grandparents set their clocks for this very reason. That inspired his most recent project – a digital clock that’s intuitive to use. Many digital clocks work i ...

We’re used to our computers being powerful enough in both peripheral and processing terms to be almost infinitely configurable under the control of software, but there was a time when that was not the case. The 8-bit generation of home computers were working towards the limits of their capability just to place an image on a TV screen, and every component would have been set up to do just the job it was inte ...

Arduino enthusiasts or those looking to build a DIY binary clock may be interested in a new shield created by developer Marcin Saj. The Arduino binary clock shield has been made available via the Crowd Supply website with preorders starting from $33 and worldwide shipping available from $6, and commencing during August 2019. Watch the overview video below to learn more about its features real-time clock and ...

After covering a few of his builds at this point, we think it’s abundantly clear that [Igor Afanasyev] has a keen eye for turning random pieces of antiquated hardware into something that’s equal parts functional and gorgeous. He retains the aspects of the original which give it that unmistakable vintage look, while very slickly integrating modern components and features. His work is getting awfully close to ...

Vacuum fluorescent displays (VFDs) are one of those beautiful pieces of bygone technology that you just don’t see much of anymore. At one time they were a mainstay of consumer electronics, but today they’ve largely been replaced with cheaper and more energy efficient displays such as LEDs and LCDs. While they might be objectively better displays, we can’t help but feel a pang of regret seeing a modern kitch ...

What do you do when you want to design ‘something’ with a vintage or modern display? A clock of course, and this is our first design with RGBDigits: multi-colour 7-segment displays. With a BME280 breakout board attached it will also display temperature, humidity and air pressure. The clock is controlled by an ESP12 module, which makes it possible to synchronise the clock with an internet time server, change ...
